exercise 22? In exercise 21 you need to make a heading (h3) and a paragraph, then in this exercise you should add a paragraph, so then you should have one heading and two paragraphs.
You need to do this, otherwise you have a problem in the next exercise. I recommend to revisit exercise 21
for next time, use one of the two following options to make your code/indent is visible:
select your code and press ctrl + shift + c (or cmd + shift + c if you use a mac)
if this instructions are unclear, you can also insert 3 backticks before and after your code, like so:
the backtick is located above the tab key on your keyboard
